A strong opponent is a dream come true for every sports champion. It's a chance to take your art even further and face off against a never-before-seen threat. But what if your opponent isn't someone you can look in the eye, shake hands or watch their reactions? In March 2016, multiple world champion and current top Go player Lee Sedol faced such a challenge. He took on Google's DeepMind invention, the AlphaGo computer, in five matches. What was supposed to be a celebration of human intuition beyond the reach of machines turned into an alarming statement about the potential power and creativity of artificial intelligence. The match Sedol vs. AlphaGo soon turned into a game of humans vs. machine, whose documentary processing evokes strong emotions.
